Putting Moodle Javascript in Yahoo's namespace doesn't cause any problems but it doesn't seem quite right. Doing a search through the moodle 2 codebase for "YAHOO.namespace(" shows there are 12 points where we are adding stuff to Yahoo's namespace. There are several options:

1) Move to the global namespace or our own namespace and provide some infrastructure to flag name collisions. Yahoo's code is currently doing this for us.

2) Continue to use Yahoo's name space but use a consistent naming scheme that makes collisions extremely unlikely. In some places we use names like "moodle.container.calendarpanels" while in others we just use "graderreport". "moodle.blah" makes it exceptionally unlikely any collisions will ever occur and logically groups our code.

any other options?
